Aliens bursting out of people's chests. Who doesn't love 'em?

This Alien* puppet was originally made as part of my deep"deep sea diver / alien victim"Halloween costume, but it was so time-consuming that I considered it a worthwhile standalone project in its own right.

I have seen various chestburster props and costumes before, but I think this one is unique for being mobile and able to actually burst out of your chest (or anywhere else you're willing to conceal your arm) rather than being permanently mounted in one position. And it freaks the heck out of cats, which is nice.

In this Instructable, I'll be illustrating some general principles that can be used for making all sorts of latex model, particularly puppets; I hope that it will be useful for anyone interested in experimenting with latex mouding.

To make your Alien, you're going to need a few things:

- Plasticine. Lots of it. More than enough to cover your whole forearm.
- A couple of plastic bottles roughly the width of your forearm or slightly smaller.
- Thin but stiff card, e.g. from a cereal box.
- Sticky tape.
- A few kilos of plaster. I recommend using specialist hard modelling plaster or resin plaster from an art supply shop for at least a kilo of this, but the rest can be generic plaster of Paris.
- Cotton stockinette or similar mesh-like material. You can use ready-made plaster of Paris bandages for this, if you happen to have them.
- Liquid moulding latex (about 2 litres).
- Baby powder or talcum powder.
- Superglue
- Paint. Latex paints if you want the paint job to last or watercolours if you don't mind repainting it each time you use it.

- Tools for sculpting. You don't need anything fancy, just something pointy and something slicy. Maybe something slightly rounded and blobby if you like.
- Old toothbrush.
- Scissors
- Paintbrush and/or airbrush

- Newspapers or plastic sheets to cover your work area. You will get messy. You'll also be producing quite a lot of unpleasant latex fumes, so it's best to work in a well-ventilated area where the smell won't bother anyone else.

Got everything you need? Splendid. The plan is to make your Alien out of plasticine first, cast a negative mould in plaster, then use that to cast the final latex puppet. OK? Let's get sculpting your little monstrosity.

Recommended listening: You've got a friend in me or I've got you under my skin.

*I'll continue to capitalise this word to distinguish it from other aliens which aren't based on the wonderful creations of H. R. Giger for the Alien film franchise. I'll also continue to spell lots of words in a slightly peculiar way because I'm British. Sorry.

Step 1: Begin Sculpting

Start by bending some strips of plasticine around your hand to judge the size and rough shape of what will eventually be the skull and jaw of your Alien. You're eventually going to have your hand inside a puppet-head of this size, so make sure it's comfortable. Join them together to make a sturdy basic head. Put this petite plasticine proto-puppet-head aside for now.

Fill the two plastic bottles with water and make sure they're sealed tightly. Having the bottles full gives them some ballast and makes them a lot easier to work with. Wrap a layer of plasticine around each bottle to make a tube. Don't remove the bottles.

In the image below, I've already sculpted some basic skin texture and body segments onto one of the the plasticine tubes. This will eventually form the lower body of the Alien. You don't have to do this yet if you'd rather get on with sculpting the fun bits.
<p>Here it is! Thanks for the terrific instructions! With it, I won first place in the Fargo Hoppy Halloween Theme Beer competition in 2015.

I've Been Looking For One Of These! How Much Would It Cost For You To Make Me One Of These From Your Mold?
Great work!
I'd just like to say, though I looked at this because it was intriguing rather than me having the equipment to make this, your comments made me Lol...especially the song suggestions xD <br> <br>Amazing project :D
THIS IS REALLY COOL now you need to make a face hugger :)
It's so cute :3
it's not cute at all... X(
A wonderful creation, great artistry, and a very humorous and informative Instructable. Excellent all around!
This puppet was awesome in Spaceballs
i love this puppet!!!!! do u make them for others???? also how much did he cost to make?? im english too so in pounds please lol?? i sooooo want one xx
Thanks for your enthusiasm, lubulldog.<br><br>So far I've just made a couple of these as Christmas presents for friends, but I could in theory make more. If you're serious about wanting one, then send me a private message.
This is Freakin' awesome dude
name it &quot;chester&quot;
<br> Thanks guys!<br> <br> And just because Mikeasaurus asked nicely, here's a tech demo!<br> <br> <div class="media_embed"> <object height="385" width="480"><param name="movie" value="http://www.youtube.com/v/J3udO3FkaoA?fs=1&amp;hl=en_GB&amp;rel=0"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed allowfullscreen="true" allowscriptaccess="always" height="385" src="http://www.youtube.com/v/J3udO3FkaoA?fs=1&hl=en_GB&rel=0" type="application/x-shockwave-flash" width="480"></embed></object></div> <br>
Great stuff!
please, tell me you have a video of this in action!
Curse you, Red Baron! I was hoping to get to both of these, but you beat me to it.
I strike again!<br> <br> Also, I was reminded of this:<object height="385" width="480"><param name="movie" value="http://www.youtube.com/v/Sh1exCwGiY0?fs=1&amp;hl=en_US"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed allowfullscreen="true" allowscriptaccess="always" height="385" src="http://www.youtube.com/v/Sh1exCwGiY0?fs=1&hl=en_US" type="application/x-shockwave-flash" width="480"></embed></object><br> :&nbsp; <a>link</a><br>
gotta love spaceballs...
Awesome work! Singing and dancing alien would be a nice touch - rig it up to sing happy birthday and you can use it in childrens parties too.
I'm working on making a whole chorus line of the little chappies...
amazing thing ever!<br>I loved it!
